Formation

Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

More about Charnockite and Metapelite

Here you can know more about Charnockite and Metapelite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Charnockite and Metapelite consists of mineral content and compound content. The mineral content of Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz and mineral content of Metapelite includes Albite, Chlorite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Charnockite vs Metapelite, the texture, color and appearance plays an important role in determining the type of rock. Charnockite is available in black, grey, orange, pink, white colors whereas, Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors. Appearance of Charnockite is Veined or Pebbled and that of Metapelite is Banded. Properties of rock is another aspect for Charnockite vs Metapelite. The hardness of Charnockite is 6-7 and that of Metapelite is 5-6. The types of Charnockite are Enderbite whereas types of Metapelite are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Charnockite is white while that of Metapelite is . The specific heat capacity of Charnockite is 0.84 kJ/Kg K and that of Metapelite is 0.72 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Charnockite is heat resistant, wear resistant whereas Metapelite is heat resistant, impact resistant, pressure resistant.
